Y XLR splitter cables?

[Firebrand]

Guys,

I'm almost done completing my purchases to have a working amplification setup for my congas. I have a Behringer 6 channel non-powered mixer connected to a Behringer EuroLive powered speaker and some of those Karmaaudio.com K-Micro microphones, plus cable.

The setup will look like this. One dedicated channel and mic cable for the Quinto, to have its own EQ. Two other microphones will pick up the remaining congas (whether Conga and Tumba, or Conga, Tumba, and Super Tumba). I'd like to pick up the other congas with those 2 microphones, but, use only channel on the mixer. Therefore, I'd like to mix the signals from both mics via a Y - One Male to 2 female XLR cable and use only one channel on the mixer.

Ive done some preliminary looking on Musicians Friends and Amazon, but, I'd like to make sure I'm finding the cheapest deal on that.

Can I get some suggestions from others who do something similar with their sound setups? Anyone else use Y mic cables for their "auxiliary" congas?

Firebrand,
There are some downsides to using Y-cables to mix incoming signals. Using Y-cables for outgoing signals, ie one amp out to 2 speakers or 2 headphones, usually works fine, but for incoming signals, the electronics can be tricky and the sound often suffers. First, the Y-cable will connect the mics in parallel, halving the mic impedance as seen by the mixer preamp. This may or may not produce acceptable sound with your mixer. It will change the relative volume of the dual mic channel versus the single mic channel, making it harder to balance the sound of the 3 mic setup. One of the reasons mixers don't use simple parallel adding of signals is to avoid this problem, that is why we use mixers to mix incoming signals. If you want to try it and see if the sound is acceptable for each mic, just make sure you test it at the same gain settings you will be using on stage. You can get a decent quality Y-cable here:

Have someone else play your congas, so you can listen from a distance. Trying to listen to the sound quality of the amplified sound while you are playing is hard because you mainly hear the direct sound from the drums over the amplified sound from the speakers. By the way, Audiopile sells a lot of decent pro-quality sound reinforcement stuff at great prices, EWI is a decent brand, much better than Hosa and house brands sold in music stores.

Even if the sound is ok at that stage, there is another practical issue to consider. If you position your drums and mics so the sound from each drum is at the volume you want, you will still not have the ability to use the mixer to separately adjust the volume or to EQ the different drums. Once you determine the exact mic location that gives your different drums the relative volumes you want, if during the set one of the mics gets moved relative to the drums, one drum will sound louder than another, and you will have to move the mic back to its original location while you are playing. A couple inches can make a big difference. With separate channels for each mic, you or the engineer would be able to simply cut the volume on one mic or raise it on the other. If the tumba sounds better with a little bass boost and the conga sounds better without it, you won't be able to adjust these separately on the mixer unless they are mic'ed separately and go to different channels on the mixer.

If you are using the 6 channel mixer as a submixer to feed one or two channels of congas to the main mixer, you should have plenty of channels to give each mic a separate channel. If your entire band is using the 6 channel mixer, you should consider getting a 4 or 6 channel mixer yourself to use as a submixer. Even if you sing, you can still fit 3 conga channels and a vocal channel on a 4 XLR input mixer. Then you could mix those 3 or 4 channels and send one (congas) or two (congas and vocals) channels to the main mixer. That would give you some control over your own sound and still give the engineer some control over overall levels for feedback control, total balance, etc.

So you suggest I go direct? The Behringer submixer is mine alone and it has at least 4 XLR mic inputs (two other 1/4 jack inputs as well). I have 7 mic cables (backups for the future), so I have the equipment necessary to go direct...but I figured that might be using the channels more efficiently with Y splitters. Good to know that there may be complications with the mixer if I do mix the signals.

In that case, I might be all set with my equipment. Let's hope the K-Micro mikes from Karmaaudio.com do a good job of capturing congas (they're designed for drum kit micing).

Alafia Abures!
I hope that you are all well and abundantly blessed mis hermanos!

Abure Jorge is absolutely correct, and quite eloquent in his explanation of the application of the "Y" cable. I have three of them, two of the ones he gave you a link to and 1 Monster Cable "Y". The safest application I use them for is when I do certain gigs with two drums only (when I'm just feeling not up to carrying 4 drums to a gig), these are some times corporate, or even bar gigs. I will either just mic the two congas, connect the cables to a "Y" splitter and send the signal out to the house PA (Bar gig), or the main (corporate gig).

The sound is impacted by this type of mic connection, mainly the mixing is severely limited, but then you must make that decision to use them. I find them pretty handy. Sometimes I use them when I don't take my mixer and use only two congas along with my Mackie Powered speaker. I just mic and connect directly into the Mackie using a "Y" cable, end of story. It's a question of convenience vs. sound integrity. I have them in my 'gig' bag, just in case.

Suave!
